1. A system for attaching a handguard to a firearm comprising:

  • a handguard comprising a handguard receiving end, a handguard receiving end portion, an exit end, and a cavity having a length extending through the handguard from the receiving end to the exit end and sized to receive a firearm barrel therethrough, a portion of the cavity extending through the handguard receiving end portion and configured to receive an attachment mechanism therein, said cavity having a normal size along the length which is rigidly formed by a portion of the handguard;

    an attachment mechanism for attachment to a firearm receiver, wherein the attachment mechanism is inserted into the cavity extending through the handguard receiving end portion to attach the handguard to the firearm;

    a projection extending from one of the attachment mechanism or the handguard;

    a receiving recess in the other of the attachment mechanism or the handguard configured to align with and receive the projection when the handguard receiving end portion of the handguard is properly positioned with respect to the attachment mechanism and adapted to prevent relative longitudinal movement of the handguard with respect to the attachment mechanism when the projection is received in the receiving recess;

    wherein the normal size of the cavity extending through the handguard receiving end portion closely receives the attachment mechanism whereby the projection is received in the receiving recess to not allow the attachment mechanism to slide into or out of the normal size cavity; and

    an assembly for manually resiliently increasing the size of the cavity extending through the handguard receiving end portion from the normal size to an increased size to allow the attachment mechanism to slide into or out of the cavity extending through the handguard receiving end portion when the cavity has an increased size.
